If there is a distillation stove for extracting mountain goo seed oil, it can also be used to extract ginger oil. The main equipments are distiller (consisting of stove, large iron pan, sealed barrel, and air pipe), cooler (composed of cooling pipe and cooling bucket) and oil-water separator.

Third, oil and water separation. The ginger oil in the ginger material is vaporized and then formed into a mixture with steam to be led out by a conduit. The oil is cooled and becomes an oil-and-water liquid and flows into the oil-water separator to obtain pure and high-quality ginger oil.
